Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

The metamaterial structure the team designed is made of a single linear elastic material. (Courtesy: Yi Chen, KIT) An unusual type of sound wave that can travel backwards in space and has previously ...

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

We visit a recording studio to explore the properties of sound. Unit 6 Segment B: Sound Waves Properties We visit a recording studio to explore the properties of sound. We explore the speed of sound ...
